No. If the power supply V3.3 of the chip is not connected with the ground, the chip will reset or work abnormally, but it will not cause a short circuit between V3.3 and the ground. In the design of chip power supply, pull-up resistors are usually added to ensure that the chip can work normally after being powered on or reset to avoid unexpected anomalies. If the pull-up resistor is not connected, the reset level of the chip may be unstable, resulting in the chip not working normally. Therefore, when designing the circuit, it is necessary to reasonably select the power supply voltage and circuit parameters according to the specifications of the chip and the data manual, and add corresponding circuit elements such as pull-up resistors as needed to ensure the safety, reliability and stability of the circuit.
